I shot the 06 for yrs with the core lokt. I had absolutly no complaints with it. The last three yrs I've hunted with the 270 and did'nt fare as well using the core lokts with it. I have started using ballistic tips and now I ca'nt find anything to critisize the 270 for. But for some reason I find myself pulling the old 30/30 down more often now as I head out to the deer woods.
